Description

卡合式液晶模块 技术领域
本发明涉及一种液晶模块，特别是涉及一种卡合式液晶模块。
 背景技术
液晶显示器(liquid crystal display，LCD)是利用液晶材料的特性来显示图像的一种平板显示装置(flat panel display，FPD)，其相较于其它显示装置而言更具轻薄、低驱动电压及低功耗等优点，已经成为整个消费市场上的主流产品。然而，液晶显示器的液晶材料无法自主发光，必须借助外在提供光源，因此液晶显示器中又另外设有背光模块以提供所需的光源。
一般而言，背光模块可依其规模的要求，以灯管的位置做分类，发展出侧光式(Edge lighting)结构与直下型(Bottom lighting)结构。其中，侧光式结构的发光源为摆在侧边的单支光源；直下型结构的光源则放置于正下方。背光模块所用的灯管须具备亮度高及寿命长等特色，目前有冷阴极萤光灯管(Cold cathode fluorescent lamp，CCFL)、热阴极萤光灯管、发光二极管(Light emitting diode，发光二极管)及电激发光(EL)等。在环保意识高涨的今天，由于发光二极管(LED)做为背光光源比冷阴极荧光灯管(CCFL)具有节能环保等优势，因此以LED取代CCFL已是背光发展的趋势。并且，通过以LED作为背光源，液晶显示器或液晶电视更可朝向窄边框的设计方向来发展。
请参照图1所示，图1是现有的液晶模块的侧剖视示意图，在此特别说明的是，为了说明上的方便，本图中的内容是以简化示意的方式来呈现。一现有的液晶模块90包含一背板91、一导光板及光学膜片组92、一胶框93、一液晶面板94及一前框95。所述背板主要用于承载光源(未绘示)及所述导光板及光学膜片组92；所述胶框93由上向下套设于所述背板91外侧并固定所述导光板及光学膜片组92以形成一背光模块；所述胶框93上承载所述液晶面板94；及所述前框95固定所述液晶面板于所述背光模块上。然而，在液晶模块90的组装中，还需要通过螺固的方式来组装所述液晶模块90或将整个液晶模块90固定于一显示器外框中，但不论是以垂直或水平方向来设置的螺固元件，都需要占据所述液晶模块90额外的体积，除了增加组装步骤外，也不利于液晶显示器朝向窄边框设计的发展趋势。

请参照图2及图3所示，图2是本发明较佳实施例的液晶模块的侧剖视示意图；及图3是图2的局部放大图。在此特别说明的是，为了说明上的方便，本图中的内容是以简化示意的方式来呈现。本发明一种卡合式液晶模块100包含一底板10、一液晶面板20及一胶框构造30及一前框40。所述底板具有一底面11及由所述底面的边缘向上延伸的多个侧面12，其内设有光源(未绘示)及一导光板及光学膜片组13；所述胶框构造30呈方框状，其内侧面中段具有一内凸块31以及其外侧面中段具有一第一凹槽32，其中所述内凸块31以下形成一第一容置空间S1，所述内凸块31以上形成一第二容置空间S2，所述第一容置空间S1套设于所述底板10的侧面11，并且所述内凸块31固定所述导光板及光学膜片组13；所述液晶面板20设于所述胶框构造30的第二容置空间S2内；及所述前框构造40由上向下套设于所述胶框构造30外侧并固定所述液晶面板20，其内侧面中段具有一第一凸缘41，所述第一凸缘41对应卡入所述胶框构造30外侧面的第一凹槽32，以卡合所述前框构造40于所述胶框构造30上。
请参照图4所示，图4是本发明第一实施例的胶框构造及前框构造的立体示意图。所述前框构造40包含四个分开的侧壁部(未标示)，以使所述侧壁部具有向外微开的弹性。所述第一凸缘41设于所述前框构造40侧壁部的内侧面，以对应卡入所述胶框构造30的第一凹槽32。另外，所述前框构造40侧壁部的外侧面中段对应所述第一凸缘41形成一第二凹槽42。
再者，所述胶框构造30的第一凹槽32的截面形状优选为一半圆形，以利于卡合作用，但本发明并不限制所述第一凹槽32的形状，如图5A所示，一种截面呈三角形的第一凹槽32a；或如图5B所示，一种截面呈梯形的第一凹槽32b。
因此，在本发明的所述液晶模块100的组装过程中，通过所述卡合式框架构造，使本发明不需要通过螺固的方式来组装所述前框40，而是以卡合的方式组装所述液晶模块100，因此可节省螺固元件占用的体积，除了可简化所述液晶模块100的框架设计外，并进一步有利于液晶显示器朝向窄边框设计的发展趋势。
请参照图6所示，图6是本发明第一实施例的液晶模块组装于一显示器外壳的侧剖视示意图。所述液晶模块100外另设有一显示器前框51与一显示器背框52，所述显示器前框51与所述显示器背框52包覆所述所述液晶模块100。所述显示器前框51的内侧面中段对应所述前框构造40的第二凹槽42设有一第二凸缘511，所述第二凸缘511对应卡入所述前框构造40外侧面的所述第二凹槽42以卡合所述液晶模块100。因此，本发明不需要设计额外的固定所述液晶模块100的螺固元件，可简少螺固元件可能占据的体积，并且还可简化组装步骤，有利于液晶显示器朝向窄边框设计的发展趋势。
请参照图7所示，图7是本发明第二实施例的背光模块及前框构造的立体示意图。本发明第二实施例的液晶模块与本发明第一实施例的液晶模块不同之处在于：卡合住整个液晶模块100的构造是由设置于一背光模块60外侧面中段的第一凹槽61与所述前框构造40的第一凸缘41来完成。所述背光模块60的外侧面可能是背板、胶框或其它部位，本发明并不限制。另外，所述前框构造40包含二个对应分开的侧壁部，以使所述侧壁部具有向外微开的弹性。通过所述卡合式框架构造，以卡合的方式组装所述液晶模块100，可简化所述液晶模块100的框架设计。
综上所述，相较于现有技术中，需要通过螺固的方式来组装液晶模块，除了增加组装步骤外，也不利于液晶显示器朝向窄边框设计的发展趋势。在本发明中，通过一卡合式液晶模块100，设置于一胶框构造30或一背光模块60外侧面中段的第一凹槽32,61与所述前框构造40的第一凸缘41相卡合形成所述液晶模块100，其可节省固定螺固元件占用的体积，除了可简化所述液晶模块100的框架设计，并进一步有利于液晶显示器朝向窄边框设计的发展趋势，并且可配合相应的显示器外壳进行不需螺固元件的组装作业。
本发明已由上述相关实施例加以描述，然而上述实施例仅为实施本发明的范例。必需指出的是，已公开的实施例并未限制本发明的范围。相反地，包含于权利要求书的精神及范围的修改及均等设置均包括于本发明的范围内。
